Can I use the MOCREO sensor in my refrigerator, freezer, or walk-in cooler?

However, there are a few important things to keep in mind:

  1. ST3/ST6 Sensors are not suitable for use in low-temperature environments such as refrigerators.

    • In fact, due to the specific structure of ST3/ST6 Sensors, they are not suitable for monitoring temperature inside refrigerators or other low-temperature environments. Prolonged deployment in low-temperature conditions can cause frost to accumulate on the surface of the Sensor’s casing, potentially leading to hardware damage through the pre-existing holes in the casing. If your requirement for monitoring environmental humidity is not particularly necessary, based on your application scenario, I would recommend using the ST5 Sensor instead (a temperature monitoring sensor that operates based on BLE wireless communication technology). It comes with an external temperature probe. During operation, you simply need to place the external temperature probe near the area you wish to monitor temperature, while keeping the Sensor body outside the refrigerator. This setup ensures accurate data monitoring and maintains stable communication between devices.

  2. ST4/ST5 Sensors are better suited for deployment in low-temperature environments such as refrigerators.

    • Metal objects have a significant impact on the transmission of signals for Sensors, to the extent that they can pose a threat to the normal functioning of the Sensor.Because all refrigeration units contain a large amount of metal, if you are going to be using our sensors in a refrigerator, freezer, or walk-in cooler scenario, use the ST4/ST5 sensor with a temperature probe.

  3. ST10 Sensor is suitable for data monitoring in ultra-low temperature environments.

    • If you have a need for monitoring ultra-low temperature environments, we recommend using the ST10 Sensor. It is a low-temperature monitoring sensor that operates based on BLE wireless communication technology and can be deployed in ultra-low temperature environments with a minimum temperature of ≥ -328℉.
